JAMES R Be itknownthatwe, HERBERT T. HERB, Gao'vrns, andDAvn) H;.FOREMA-N, all. citizens of. the United States, residing in the'c'ityand county of. Denver; and State of Colorado, have invented certain new and useful. improvements in; Dumping -Cars; BJISi-fWG doxleclaro the-following to be afull, clear, and exact description of the invention,

such. aswill, enable others skilled in the art to whichit: appertains to make and use the same, reference being had to the accompanying drawings, andpto the letters and figures: of reference marked thereon, which form a part of thisspecification.

ur invention relatesto improvements in.

dumping-cars, and is more particularly adaptv edtothe constructive type of dump car-body may be.

havin a centrally disposed: longitudinal tnuss cam or a frame, with end floors inclined. downwardly, at a suitable angle from the ends, tothe central portion of the car body; on. tethebottom of. which are secured two.or-more longitudinally hinged dumping or. discharge doors! A novel and important feature embodied inv our invention, which we believe to. be spe cifically new, and a. radical departure from existing details in. this class of construction, isthemeans whereby we secure the discharge doors. to the bottom of the car body with a hinge-lockor hinge-locking cam by the use of which. we are enabled to release the discharge doors from. either-their inner or outer edges, while the engaged members upon the opposite sides. of. the doors act as a hinge,

around which the released; doors swing, either inwardly or outwardly as the case This arrangement enables us to discharge the entire load upon either side of the track, or between the rails of the track, or'in. part upon either side of the track, or in part between the rails of the track and upon either'side of the track as conditions may require. (Dur c nstruction furtherafi'ords in either of these several dumping positions a maximum area abling us thereby to dischargethe entire load very quickly, ii so desired, entirely automatically, by gravity, requiring no. hand shovelof the load,

mg of any portion the 11" bodies a further novel andimportant fear of open dumping space en-- Our II1VBIIUiOIi.CCJ1l1PIlSOS a winding mcchanism whereby'thc released doors may be lifted. and replaced in position, and pro ,erly secured by the hinge locking cams for re cad,- ing the car. Considering. the several posi tions into which, the doors may be dropped, from any of which they can be replaced 'by this winding attachment, the construction, is comparatively quite simple, eflicient and durable.

Our invention further comprisesa footbrake'mechanism, mounted upon. the winding mechanism whereby the operator is enabled to fully control thespecd with which the loaded doors are permitted to drop, thereby avoidin the danger of; damaging the construction from the impact of; the heavily loaded doors, were they permitted to drop freely u on the arts. This foot-brake attachment also enab es the oponator to gov cm the distance towhich the doors are permitted to open, and with an interlocking pawl and ratchet suitably" mounted upon. the winding mechanism, secure them in any partly openedv position, when. desired to particularly control'the discharge of the material being dumped.

0H1 invention further comprises a novel combined construction, whereby the initial movement of the door-releasing operating levers automatically throws the hand-cnank winding mechanism. out of engagement with the winding gear connected; with the. dis charge doors, rendering the crank-winding mechanism, entirely inoperative for the time being, for the purpose as shall hereinafter be fully set fort is further provide for positively securing the door-releasingoperating levers, automatically, in their closed positions, for the purpose of preventing the accidental release ()1 the door hin e-locking cams, of the load While in transit;

In this present application we describe and illustrate, merelyin a general way, a construction of dump car adapted to embody our invention referring specifically to only so muehof the car body construction as is necessary to enable one skilled in the art, to tally and clearly comprehend the construction, application and cooperation of our invention. Y

Referring to the drawings, briefly stated,

'we provide in the car body construction a central longitudinal truss-beam, being in cross section an A-shaped plate member A, Fig. 7, the lower edges of which are transversely supported by a number of tie-bars A, formed by angle bars, secured to the sides thereof, on a line with the door beam hanger looks as shown in Figs. 2 and 7, and side channel beams or car s-i-lls B. B. and floors O Figs. 1, 23 and 24,5incliried downwardly at a suitableangle fronnthe ends of the car body toward the central portion thereof, at the-termination'whereof are suitably disposed tiansversebeams D. D. Figs. 1, 2, 23 and ,2;4'," thus. forming in the central bottom portion of a two-door car body between the sides of the central truss-beam member and the adjacent respective side sills and cross-beam members, two rectangular openings of suitable area; while in a fourdoor car body these somewhat elongated openings are bisected centrally by transverse Afshaped truss-beams E E, as shown in Figs. 23 and 24, thus forming four rectangular openings of a proportionally increased total area. These openings in the two-door car are fitted With suitable discharge doors, F. .G. Figs. 1 and'2, and in the four-door car with four discharge doors, F, G Hand I Figs. 23 and 24. It will be understood that we do not limit ourselves to this numberof openings and doors, since under certain conditions a with probably diminished areas of openings would be desirable. Referring to Fig. 7, we indicate in broken lines the several positions into which the doors may be dropped, also in broken lines the several corresponding positions from either of which the doors can be carried up to their respective closed positions by two longitudinally disposed crank shafts 22, 22.

In diagram Figs. 3 to 6*, Fig. 3 showsthe doors set to discharge the load to the outer sides of the track Fig. 4 to the inside of the track; Fig. 5 partly to the right hand side and partly between the track rails; Fig. 6 partly to the left hand side and partly between the track rails; Fig. 6", with th.e door F released, and the door G closed; Fig. 6

Cast integrslly wits this flanged base and extending dowi'iwsrdly from the sides thereof, two lon iidinolly bored joint-pin lugs '1, upon the too of one of which is formed a longitudinally slotted boss 1 which serves a guide or carrier for a. coniiiecting her 4-, mounted upon which, adjacent the hi e-loeh .-pin 4 designed to register with, and be engaged by the oored hanger lugs 1 The hinge lock shown in Fig. it) is substantially a duplicate of that shown in Figs. 8 and 9 described sh eve, excepting that on this the flanged hose 1 and the bored joint-pin lugs l are disposes relatively at a slightly dili'ci ent angle, and the flanged port 1 formed double or as s jaw-flange, designed to be secured to, and conform with the sloping sides of the central truss bee-n1 A.

On to the under sides of the discharge doors i and A. are secured s'corresponding number of trsnsversely disposed door besi'n hinges 3 3, the ends of which, projecting slightly beyond the sides of the doors, are formed into joint-pin eyes, or hinge ends 3*, 3 designed to register with the slotted spaces formed between the bored hanger lugs 1, i oi the hinge-locks, in which position they are engaged by the cooperating joint- )lDS & as shown in 8, 9, its) and 1'7. Reierrii'ig to Fig. 12 it will he soon that the end ofthe joint-pin 4 is tapered at suitable sing 4 to permit of its taking-rip to some extent, e sagging door hinge 3", when the pins thrust home, and erlgsg the hinge end between the iILH C-J lugs 1*, y in the connecting 4, r. iese are suitably disposed, one each sdpining the si sills B, B of the. car, and two beneath the central truss beam A, each mounted in th r respective hanger slots 1 and the several joint-pins 4i", as shown. in rigs. Zsnd 7. The extreme end of each bar t, 4, i, e adjoining the operative end of the ear is jointed, respectively, to vertically disposed operating lovers 5, 6, 7 and 8, as shown in eleased. end, the door l end 7 all doors in closed "Figs. 1, 2 end 414, each mounted on it suitable bearing, 5 6", 7 or 8*. Upon the side of each lever, above the bearing is formed, respeetively, a stud 5, 6", 7 or 8, each of which engaged by a self-noting retaining hook 9, 9, 9, 9, {tS-SllOW'H in Figs. .41, 42, -13 and M, positively securing; the leyers in the position corresponding with the normally ongaged position ol" the joint pins l preventing the accidental disen the joint-pins, and release of the discharge doors.

The connecting bars 4 and 4. are respectively, suitably secured to a joint-pin tube 4 and a jointsive. As W1 1 be seen these tubes carry the joint-pins 4 cooperating with the hinge-locks.

engaging the hinge ends on both sides of the doors F and G, and in like manner the rods 4 carry the joint-pins cooperating with the hinge locks, engaging the hinge ends on both sides of the doors H and l. Central aliriement of the joint-pins is secured by passing I the end of the rods 4 adjacent the connect ing bars 4 through the tubes l in which they take, free bearing. Suitably enlarged pin-yokes 4 are secured to the tubes 4' as shown in Fig. 31, the hanger guides 1", Fig. 29, being designed to conform to the tubes 4' and the rods 4 To release the outer sides of the doorsF and G as shown in Figs. 23 and 24, while the doors H and I remain closed, all the operating levers 5, 6, 7 and 8 being secured in the closed position shown in Fig. 1,

the operators first disengage the toe of the shoe raise the inner slotted heads of the bars 4 and rods 4 up, into the inoperative position shown in Fig. 3.4, lifting the recess 10 out of engagement ,with the lever stud, simultaneously interlocking the lug 10 with the lockin bracket 11, the recess 10 of the adjoining s otted head remaining If the levers now be moved in the direction of the arrow in Fig. 34, the stud passes into the slot of,the disengaged head, thereby interlocking it against longitudinal n1ovement,,and secur ing the doors H and I against accidental re lease. Meanwhile the bars 4 and slotted heads are being moved in the direction of the arrow, simultaneous with which movement the plane surface 10 ofthe moving head hecomes interlocked under the bracket 1]., thereby preventing their jumping up and accidentally releasing the studs during the the position shown in Fig. 23. Enough clearance is given the parts to permit the slight radial displacement of the lever studs. Inasmuch as the bars 4" connect with the tubes 4 the 'oint pins 4* are withdrawn from the outer hinge ends of the doors F and G, permitting them to drop and discharge a portion of the load. The earthen being moved to spot the doors H and I, the levers 5 and 8 meanm rod 4 Figs. 23 to 35 incluthe retaining hooks 9, 9 from the levers 5 and 8, and with 'time having been-returned to the position shown in Fig. 1, the disengaged slotted heads dro by gravity into engagement with the stu s. The leverslare again moved in the direction of the arrow Fig. '32, carrying with them the bars Hand-rods 4 releasing the doors H andl, a'ndcarrying the bars 4 and tubes 4" idly'along. It will be understood that by first disengaging the outer slotted heads and bars 4 the doors H and I may be released first, while F and G remain closed. It will also be understood that if it is desired to release either side doors simultane-v ously as F and H, the lever is simply thrown with both slotted heads in engagement, as shown in Fig. 32. From the above descriptionit'will be readily comprehended that oy the manipulation oi certain levers, iri combination with certain ones of the slotted heads, any of the several discharge positions can be effected in unison with any of the several combinations possible in the four doors. From the above it will also be seen that all doors can be entirely disengaged and convenientl moved aside, making all parts of the detail construction readily accessible to me- )ehanics or car repairers, it necessary.

Figs. 48 to 58 inclusive illustrate a hingelocking cam, being an alternative construction of the joint-pin hinge-locks hereinbefore described, a locking cam taking the place of the joint-pin, in engaging and support-in the discharge doors, the hinge ends of whic in-' stead of being a joint eye are formed into T-ends, adapted to register with and be ened by the locking cam.

in the figures, 15 indicates the main hanger base, adapted to be secured either to the side channels B, B, of the car body, as in Figs. 48, 51 and 52, or in a slightly modified detail construction to the sides of the central truss beam A, as in Fig. 50. An angular hingeengaging flange 16 is formed integral with the main hanger 15, adjoining the lower end thereof, upon the under side of which, de-

ending from the corners, are formed 'two liinge engaging lugs 16. Also cast integrally with the main hanger 195 and extend ing downwardly from thelower end thereof, are two bored. cam supporting lugs 15*, 15, revolubly mounted within which upon a short shaft 17 is a hinge-locking cam l7, in tegrally formed upon the under side of which is a hinge-engaging jaw 17, and at nearly right angles thereto a curved crank pin arm, 17*. Upon the under side of the hanger flange 16, between the lugs 15 and 16" is formed a semicircular, transverse groove Hi", conforming to and designed to receive the round bar end of a door-beam hinge as shall. be shown. A toggle link 18, lormed upon the lowe'nend into a crank-pin eye 18*, is freely jointed to the curved crank-pin arm 17*, the opposite upper jawed end l8" be1ng jointed to a connecting bar 19. This bar Elli is'constructed, preferably, of e standard '2'- sectiou, as shovm in cross-section Figs. 48 end 50, and. is supported at each of the hanger castings in e, slotted bracket 1.5", cast integrelly u.

It will be ob served that, a powerful leverage "force is brought to bear upon the (remiss 17* because of the olosing angle, into which the to gle link 18 has been carried, thereby eneb ling the operator to effect a. complete end thoroughly tight closure of the door.

The construction whereby the released discharge doors are raised into the closed position for reloading the cm" provided in duplicete, end the ports cooperating with the door or doors upon either side of the (ontrel truss been] erei lei1tim1l, a description of either will apply to both.

In a two-door can, as shown in Fi e. 1 and 2, s. longitudinal crank sbslt 2:2, lies lonm-d thereon crank 22, slightly longer than the door. This crank slmlt is mounted in banger bearings 23, 2.; which are secured beneath the (or body adjacent, the ends of be dis charge door, substantially in :1. plane bvumlb the longitudirml (miter of i he doors, as shown in Fig. 7.

Mmmted upon be ceases cranks 22 are anunnber of antifriction rollers 245, 24;, corresponding with the number of hinge beams secured upon the discharge dooi s,.which in thefigureis shown to befour, this is optional, however, as a greater numberma-y be found necessary to meet thereqnirements of practice. The rollers are placed in position to registerwitlr the hin ecanr irons against which they roll when. t

door is beingraised by the crank, a separate roller plate-may be used if desired. We show in. Fig-Q9 a retaining stud 22 whereby the roller is secured in position upon the crank shaft 22.

Figs. to- 22 show the roller in enlarged detai whichis made up of the parts, 24, 24 joined uponv a diametrical plane parallel to the shaft engaging center 24!, by suitably disposed clamping bolts or rivets 24 engaging suitable lugs 24, adjoining the hub upon both sides of the central tread 24 formed within the plane of which, of a some"- what greater diameter than the shaft engaging center, isan interior annular groove 24- designed to-register with and beengaged by the retaining stud 22, thus securing the rollers in cooperative position with reference to the hinge-beam irons.

Referring to Fig. 7 it will be noted that the center line of the crank shaft 22, is particu larly located with reference tothe corresponding location of both the inner and outer door-beam hinges, and the length of the crank arms 22', in order to eflect the universal raising-of the door by the crank shaft and cooperating winding mechanism. This can be effected regardless of the position occupied by the crank prior to the releasing of the door, and whether the door he released from the inner or outer side.

Referring to Figs. 1, 2 and 23 it will be seen that the door ends swing freely between the crank arms 22". permitting the crank to. assume a position beneath the same when discharged, as indicated by the several positions 0 thecrank, and released door shown in broken lines in Fig. 7, from either of which positions the door can be carried back to the closed position by rotating the crank in the corresponding required direction. It will also be observed that the crank forms a hanger or stop for the discharged door, assuminga position at right angles thereto with the weight and forces exerted longitudinally through the cranka ms ing torsional forces upon the crank shaft, by the weighted door, with the danger of givingthe same a permanent set.

Secured upon the end of the shaft 22, is a bevel gear 25, which meshes with a bevel pinion 26 mounted upon the lower end of an upwardly inclined counter-shaft: 27, which is suitably supported in bearings 27, 27 adjacent the operative end of the car, disposed beneath, and at an angle conforming luble and longitudinal in the inoperative position, for as hereinafter shown.

22", thereby eliminatto the slope of the inclined end floor C. Ad.- joining the upper bearing a band-brake wheel 28 is mounted upon the shaft 27, and upon the upperend thereof is secured a bevel gear Wheel. 29, which meshes with a bevel pinion 30.. This pinion is keyed upon. the end of a short horizontal shaft 31, which forms a part of the crank winding mechanism. This construction is shown in enlarged' scale in Figs. 36 and 38, with a slightly modified arrangei'nent of the upper shaft bearing'27, as compared with that shown in, the reduced scale Figs. 1 and 23. This shaft 31 rotates freely in the bearing 27 and 1s locked. against longitudinal movement therein by the pinion 30, and a positive jaw, clutch-coupling member 82, which is also secured upon the shaft 31, several inches of the shaft extends beyond the face of the clutch member, forming a stud or axial bearing for the corresponding clutch member 33,

which takes revoluble and sliding bearing upon this shaft 31. This clutch member has a somewhat elongated hub 33 by which it is securely keyed upon the end of a crank shaft 34. Adjoining the clutch hub 33, is a loose yoked. sleeve 35, mounted freely upon the shaft 34' between the end of the clutch hub and an adjoining flanged collar 36. This collar is also securely keyed upon the shaft 34. The shaft 34 also takes both free revobearing in a supportlng member 37, suitably secured to the our bed Formed upon the.upper side of the s'ha t-bearing of this supporting member 37, is a boss 37*, upon which is mounted a right and left locking pawl 38, designed to engage a ratchet 39, which is securely keyed upon the crank shaft 34. the extreme left, brings this pawl and ratchet and the clutch members 32. and 33 into the engaged or operative position as in Fig. 36, while by moving the shaft to the extreme right as in Fig. 38, they are disengaged and the purpose The,,extre1ne right hand end of the shaft 34 is formed into a hand crank 40. i

The above described construction comprises the attachments adapted to secure, release and raise the discharged doors, providing for the opening of the doors to their maximum limit, permitting of the rapid dis-- charge of the load, ordinarily desirable when dumping coal or ore into bins or chutes. In practice, however, it is frequently necessary that the opening of the discharge doors be controlled, particularly in the case of handlin ravel or ballast along the line in road work, where it is desired to distribute the same from a moving car with the doors partly open. Weaccomplish this result by the use of a foot-brake construction. licferring to Figs. 1., 2 and 23, a hand brake wheel 28, of the usual mmstruction is secured.

Moving the shaft 34 to 'tarded crank shaft also in duplicate, the two core upon the counter-shaft 27', from which the friction strapQl is secured to a short crank arm 28 formed upon a transversely i'lisposcd rock-shaft 28, suitably mounted upon the car frame, upon the ends oi which shaft are formed two foot-tread arms 28 which carry a transverse tread board 28, located adjacent the hand-crank, and ilCCQSSlblB to the operator when operating either the inner or outer release levers. By applying the brake the dropping of the door can be controlled and brought to a stop in any part of the swing, by the engagement of the brake-re- 22, beneath the door and when so stopped can be securely retained by interlocking the pawl and ratchet 39, upon the operative-i oi winding incohanisin.

\ Referring to Figs. 3 that to raise the releasei sition shown in Fig.4. IT lien is onward u charge, the oper ps the cooperating handcrsnk 4L0, hanging downward as in i ig, 1, and rotates it out-w lly, as indicated in broken lines in Fig. in Fig. 4, which is inward dump rotate the respective hand cranks inwardly. in Fig. 5, the left side door being inward dump rotate the cooperating crank inwardly, the right side door being outer dump rotate the right side crank outwardly. Thus it will be seen that the direction of discharge is a guide to the required movementof the hand crank to return the door, conse-Qruently, even though our con struction embodies this plurality of dumping positions, confusion on the part of the o erator in manipulating the parts is not like y to arise.

If the loaded doors are released and permitted to drop freely their full swing, there is danger of damaging the winding, gear con..

struction from the sudden impact of the parts and also of injuring the operator because of the high velocity of rotation attained by the winding mechanism and hand crank'if these parts are not first disconnected from the shaft and tr in before the doors are released. To eliminate his danger and secure a positive, autonmtic disengagement of the winding gear hctore it is pr :iole to throw the orer' rel door hinge ni struction shown. in which is located a the car, and shown but which, in order i0 these reduced scale th drafted therein in iiuii,

ed to he turned down stead of the hinged looking bar 48, a hooked end locking bar 52, engaging on one end a connected reference as to the operation of the mechanism, will be readily understood. Let it besupposed that the operators wish to dump a load from the two door car, as in Figs. 1 and 2, inwardly, as shown by diagram Fig. 4. Unlocking, or unsealing the hinged locking bar 48 which they turn back from off the locking'arms 47, 47, orin the case of the hooked-end locking bar 52, which they slide to the left and permit to drop and hang in the position shown in broken hnes in Fig. 44, then, disengaging the respective retaining hooks 9, 9 from the operating levers 6 and; 7, these levers are drawn outwardly from the car, upon the initial movement of which. the s ring bolt 47 engages the crank-pin 41 Fig. 42, and as the lever is being carried forward lifts the crank into the position shown in brokenlines in Figs. 42 and 46, rotating the rock shaft and with it the hook-dog 42 permanently keyed thereon, which in the first half of this movement is lifted up out of engagement with the flanged collar 36,

shown in broken lines in Fig. 36, meantime the locking lug 42* has been carried into engagement with the lugs 43, 43 of the loosely fitting yoke arms 43, 43 rotating them during the remainder of the rockshafts rotation, carrying the hooked dog 42 from the position shown in broken lines in Fig. 38, idly up to the angle shown in full lines, and meanwhile carrying the yoked sleeve 35, with when ank shaft 34, clutch menili er 33, collar 36 and ratchet 39 to the extreme right, into the disengaged or inoperative position of the winding mechanism, as shown in Fig. 38, during which movement the ratchet 39 has slid from under the weight- 'ed pawl 38, permitting it to drop by gravity a predetermined distance, by the engagement of a stop-stud 38 with the side of the bearing 37 7, into the position shown in this fi ure, forming a positive step in the way 0 the ratchet 39, preventing thereby the accidental movement .to the left of the crank winding mechanism and rengagcment of the clutch j aws' at this time; the instant of release of the discharge doors. It will be noted that in making this automatic disengagement of the winding mechanism the shorter arm of the operating lever does not move an appremge This release movement ther noted that when the follows immediately, however, u on carrying the lever to the extreme out-ward position as shown in broken lines in Fig. 1, disengaging the door hinges upon the inner sides and permitting them to drop as shown in Fig. 4, and discharge the load inwardly. It will he furlatch bolt passes from under the uplifted crank 41 and hookdog 42 these parts drop by gravity being free to rotate with the rock shaft 41 bringing the dog 42 into the position shown in broken lines in Fig. 38, resting upon the top side of the flange collar 36. The load having been discharged, with the operating levers still in the outward osition, corresponding with the released posltion of the hinge members', to return the open doors to the closed position, the operator first lifts the pawl 38 out of the way of the ratchet 39, pushes the crank shaft 34 and Winding mechanism into the operatively engaged position shown in Fig. 36, simultaneous hook-dog 42 slides over the flanged end of the collar 36 and drops by gravity into positive engagement agalnst the collar as shown in Fig. 36, securing the winding mechanism in o erative position. The load having been disc iarged inwardly the operator proceeds to turn the hand crank 40, inwardly, adjusting the pawl 38 accordingly in engagement with the ratchet 39. When the empty doors have been carried up to the closed position, and retained by the pawl and ratchet, the operating levers are thrown inwardly, carrying the hinge-locking mechanism into positive engagement with the door beam hinges as has been shown, while enga e the cranks 41 and spring downward passmg under and automalicall y springing into positive engagement back of the cranks 41 within the housing 45, simultaneous with which movement the retaining hooks 9, 9 drop into engagement with the respectiveoperating levers 6 and 7, when they locking bar 48 can be secured over the arms 47, 47 as above stated. 1

It will be understood from the above explanation, that with the winding mechanism in operative position. as in Fig. 36, forces exerted longitudinally upon the crank shaft 34, or upon the loosely fitted sleeve yokcs 43, 43, do not tend to raise and release the hookdog 42, consequently, an operator having grasped the hand crank 40 and p rtly raised the; doors, will not, accidentally," disengage the winding mechamsm, he ordinarily might, being swung heavily to and fro against the crank, while operating upon a moving car.
